Embodiment 1

[0033] combined with image 3 As shown, a bandwidth optimization method of a TWS system includes:

[0034] The first link is established between the audio gateway and the master device, and the slave device establishes a monitoring link for monitoring the data packets sent by the audio gateway to the master device, and it is agreed that the master device sends packets to the audio gateway. The communication between the master device and the slave device forms a virtual link between the master device and the slave device.

[0035] In the present invention, based on the current mainstream TWS technology, in the initial stage of the establishment of the communication link, the audio gateway establishes a connection with the TWS main device, that is, the first link, which becomes the first physical connection, the main connection, and the TWS slave The device monitoring link is established; once the monitoring link of the slave device is established, the communication between the...

Abstract

The invention discloses a bandwidth optimization method of a TWS system, and relates to the technical field of wireless Bluetooth, a first link is established between an audio gateway and a master device, and a slave device establishes a monitoring link for monitoring a data packet sent to the master device by the audio gateway, and appointing to carry out master-slave device communication in an idle time slot of a sending time slot of sending a packet to the audio gateway by the master device so as to form a master-slave device virtual link. According to the invention, a link between the master device and the slave device, which needs to be maintained by a traditional TWS system, is omitted, and the implementation is simpler; according to the invention, after the link of the master device and the slave device is maintained, the expenditure of piconet switching is avoided, and the expenditure of data transmission of the master device and the slave device is also avoided, so that the bandwidth utilization rate of audio transmission is improved, and the audio listening feeling and fluency are better.

Description

technical field [0001] The invention relates to the technical field of wireless bluetooth, in particular, to a bandwidth optimization method of a TWS system. Background technique [0002] The TWS (True Wireless Stereo) system is a system composed of an audio gateway and two headphones, one of which is set as the master device, and the other is set as the slave device. At present, the mainstream TWS headphones use the monitoring scheme of the slave device, such as figure 1 As shown, after the master device establishes a connection with an audio gateway device such as a mobile phone, the master device sends the connection information to the slave device through the connection (link) between the master device and the slave device, so that the slave device can listen to the mobile phone. The package to the master device, so that the master and slave headphones can play the audio data sent by the audio gateway at the same time. In this case, a connection needs to be maintained ...
